Until now, we knew that ticks primarily transmit two pathogens to humans in Switzerland: the bacterium Borrelia burgdorferi – which causes borreliosis – and the early-summer-meningoencephalitis virus, which can cause cerebral inflammation.
Now, microbiologists from the University of Zurich confirm the existence of another tick disease in Switzerland – neoehrlichiosis.
Now a group including renowned climatologists and leading geoengineering thinkers Ken Caldeira and David Keith tries to investigate ways to alleviate some of the (likely) unwanted side effects of Arctic solar geoengineering.
Over the course of 2012 ENSO has moved from La Niña to El Niño state. Various ENSO forecasting models (see NOAA NECP, IRI ensemble below) now show Pacific equatorial SSTs anomalies will remain positive for the remainder of 2012 – … Continue reading →
Hypercapnia it turns out, develops much more gradually than previously assumed. Apparently long before we pass thresholds that mean real medical trouble, our bodies – and our minds – can be disturbed by elevated CO2 levels in the air around … Continue reading →
The last ice age is known for periods of high climate variability like the period between the Last Glacial Maximum and the Younger Dryas, towards its end. Also about halfway through the ice age temperatures spiked and dipped rapidly. And then about 41,000 years ago suddenly Earth’s magnetic field weakened by some 95%, allowing a bombardment of cosmic rays, and a couple of centuries during which your compass would direct you towards Antarctica. Following this Earth´s northern hemisphere experienced the biggest volcanic eruption of the last 100,000 years, which occured in Italy.
The identified critical threshold for dangerous climate change saying that the increase in global temperature should be below 2 degrees Celsius seems not to have helped the climate negotiations so far. New research from the University of Gothenburg and Columbia … Continue reading →
